-----------------------------------------
Summary: cqlsh copyutil should get host metadata by connected
address
Key: CASSANDRA-11979
URL: https://issues.apache.org/jira/browse/CASSANDRA-11979
Project: Cassandra
Issue Type: Bug
Reporter: Adam Holmberg
Priority: Minor
Fix For: 2.2.x, 3.x
pylib.copyutil presently accesses cluster metadata using {{shell.hostname}}
which could be an unresolved hostname.
https://github.com/apache/cassandra/blob/58d3b9a90461806d44dd85bf4aa928e575d5fb6c/pylib/cqlshlib/copyutil.py#L207
Cluster metadata normally refers to hosts in terms of numeric host address, not
hostname. This works in the current integration because the driver allows hosts
with unresolved names into metadata during the initial control connection. In a
future version of the driver, that anomaly is removed, and no duplicate
hosts-by-name are present in the metadata.
We will need to update copyutil to refer to hosts by address when accessing
metadata. This can be accomplished by one of two methods presently:
# shell.conn.control_connection.host (gives the current connected host address)
# scan metadata.all_hosts() for the one that {{is_up}} and use
host.address/host.datacenter
